What it does

Darwin Skill is an agent skill from HHU3637kr/skills. Darwin Skill (达尔文.skill): autonomous skill optimizer inspired by Karpathy's autoresearch. Evaluates SKILL.md files using an 8-dimension rubric (structure + effectiveness), runs hill-climbing with git version control, validates improvements through test prompts, and generates visual result cards. Use when user mentions "优化skill", "skill评分", "自动优化", "auto optimize", "skill质量检查", "达尔文", "darwin", "帮我改改skill", "skill怎么样", "提升skill质量", "skill review", "skill打分".

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 35 other files, including scripts and assets (for example `README.md` and `README_EN.md`).

It sits in Agent Workflows, covering Git workflow, Quizzes and assessments and Autonomous loops. It works with Git.

When your agent uses it

  • User mentions 优化skill
  • Tasks that involve Git workflow
  • Tasks that involve Quizzes and assessments

Example prompts

  • “优化skill”
  • “skill评分”
  • “auto optimize”
  • “/darwin-skill”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. 初始化
  2. 5: 测试Prompt设计
  3. 基线评估(Baseline)
  4. 优化循环
  5. 5: 探索性重写(可选)
  6. 汇总报告

What it can do on your machine

Read from SKILL.md and the folder at commit a2cccf6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/, which the agent can run.

    Shell commands in SKILL.md call:

    • git
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Darwin Skill loads about 2.2k tokens when it runs. Until then it costs about 119 tokens; SKILL.md has 300 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~119
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 300 words (~2,154 tokens).
